Distributed with FileTyper is MakeAutoTyper, a widely used utility for creating customized automatic changers called "AutoTypers"; and FileTyper Menu, an extension that adds a useful "FileTyper" item to the Finder's File menu.

FileTyper has become a utility of choice for many because:

It is powerful, with many useful features including batch jobs of any size, prefiltering of batches, searching of folder hierarchies, and direct editing of many file and folder flags, including uncommon ones that other utilities leave out.

It is fast, running batch jobs in a fraction of the time taken by an AppleScript droplet.

It is small, with a compact, no-frills design for maximum performance and portability with a minimum of hassle.

It is customizable, using the companion utility MakeAutoTyper. Customized AutoTypers have been bundled with many common applications such as JPEGView and SoundEdit 16.
